This invention relates to new and useful improvements in ice cream dishers.

More particularly the invention relates to a utensil commonly known as an ice cream scoop for serving ice cream in a measured form from an ice cream container. As such the invention has as a principal object, the provision of an improved construction of this character, which will be highly efficient in use and economical in manufacture.

In accomplishing the object of providing a scoop of the character more fully hereinafter described, which may be manufactured at an economical cost, it is apparent that the several parts of the scoop should be related one to the other in a manner such that assembly of the parts may be done quickl and without the requirement of a skilled mechanic.

In the process of serving ice cream from an ice cream container by means of a scoop, it is a Li known fact that substantial force must be applied to the scoop in order to pass the scoop cup into the ice cream and to scoop the ice cream therein and then withdraw the scoop therefrom.

Frequently, by reason of this undue force necessary for this operation, the scoop bends or is ruptured at the junction between the handle of the scoop and the cup. With this in mind, it is an object of this invention to provide a cup and a handle constructed in a manner such as will reduce to a minimum the possibility of breakage or bending of the handle.

Yet another and equally important object of the invention, is the provision of a scoop having a cup provided with a blade operable within the cup by mechanism which is substantially effective for that purpose and which may be operated with the minimum of effort on the part of the operator.

Other objects will appear hereinafter.

Fig. 1 is a perspective view of my improved i ice cream disher.

Fig. 2 is a bottom plan View of the same.

Fig. 3 and Fig. 4 are side views respectively of the invention.

Fig. 5 is alongitudinal sectional detail view of the same.

Fig. 6 is a fragmentary sectional detail View taken substantially on line 5-45 of 2.

Fig. 7 is a perspective View of the invention showing the parts thereof in exploded relation and Fig. 8 is an enlarged sectional detail view of the ratchet plate mounting stud.

The several objects of my invention are accomplished by the preferred form of construction illustrated in the accompanying drawings.

In this connection, my improved ice cream disher includes a cup it? within which operates a blade 23 of resilient material and preferably of relatively thin material inasmuch as the function of this blade is to sever the measured ice cream portion from the walls of the cup II].

A shank i2, having a flattened medial portion l8, has an end portion M projected into a socket 55 formed in a plate 86. This plate i6 is secured by brazing or the like to the cup it, and is shaped in its major portion to conform to the shape of the cup It. The end portion M of the shank i2 is likewise secured in the socket l5 by welding or the like. In this manner, not only is the shank 62 securely connected to the cup I 0 but the plate It substantially reinforces the point of connection between the shank i2 and the cup 10.

Formed in this plate l6, adjacent its top edge ll, is an opening 58 and projecting into this opening 58 is a rotatable shaft H3. The end 2B of this shaft 29 is bifurcated as at M to receive the angled end portion 22 of the wiper blade 23, the said end portion 22 projecting through an opening 241 formed in the cup W. The end portion 25 of this blade 23, which blade 23 is formed of resilient material, carries a pin 26 which rotatably projects into an opening 2i formed in the cup I0. I

By this structure, the wiper blade 23 is supported within the cup it for movement over the inner wall or surface thereof, to separate from such wall the measured portion of ice cream.,

The end portion 2% of the shaft Ml has a fiattened surface 25 and this portion 28 having the flat surface 29 projects through an opening 38 formed in a segment gear 3!, the flattened portion 2% serving to fix the gear 3! upon the shaft is for rotation with the latter.

Mounted on the shank i2 is a finger piece 32 formed as an integral part of a plate 33. This plate 33 has an opening S l formed therein into which projects the end 28 of the shaft l9. Between this plate 31-3 and the gear 35 is a spacer sleeve 35. The plate 33 has an opening 36 formed therein and this opening provides opposite flat edges 3'! which, when the plate 33 is mounted on the shank l2, fits against the flat surfaces 38 formed on the end portion 39 of the shank l2.

On the swaged portion 13 of the shank I2 is a bearing stud til having a groove 4| around a core 42, Fig. 8, which core 52 is substantially circular in cross section except for opposite flat sides 43. The stud if! is positioned on the shank l2 in such a manner that the flat sides 43' of the core 42 piece '52. .ger 'onthe finger piece 52,"after axportionfiof ice 3 are substantially perpendicular to the axis of the shank 12. A ratchet plate is indicated at 43 and this ratchet plate is provided with an opening 44 of a diameter to receive the core 42 and entrance to which is permitted by a slot 45 of a width substantially corresponding to the width of the core 42 between the flat sides 43'. The arrangement is such that by passing the core 42 through the slot 45, the core will be disposed in the opening 44 to provide oscillatory connection between'the ratchet plate 43 and thebearing 40. The ratchet plate 43 is spaced from the shank 12 by a rib l2 which rides upon the shank I2, as shown in Fig. 5. The ratchet plate 143:1s17provided with spaced openings 46 adapted to have meshing relation with respect to the'teeth W-of the gear 3|, the gear having an enlarged portion to limit rotation of the gear relative to the ratchet plate 43. The rib i2 maintains the ratchet 4-3 and teeth 4! in meshing engagement with respectt'o each'oth'er. It also serves to strengthen the' ratchet plate.

A 'coil spring 48 is mounted upon the bearing "40 with one end 1 portion 49 engaged in an i opening 49' formed in theswaged portion i-3iandian opposite end portion 50 hearing against a depending iiange BI provided by'the 'plate '43. This flange 51 provides an extension which serves as 'Thecoil spring *48 is related to the shank :l2

and ratchet plate 43 in a 'mannersu'chlthatnwhen pressure is applied to the finger piece '52 vof the plate 43, the gear-'31 will Ice-rotated by thissspring to the 'position'to dispose the-blade 23 contiguous the edge of the cup ll], =as shown in LFigJ-T tu'dinallyeXtending bOI'e- BB iS formed ini'therhan- "dle54f'the outer endof whichyas at mgis of a larger diameter than the remaining portion rof the "bore. In this" bore is positioned a connectin'g bolt 58 threaded *as at 59 1 into the :shank :l 2 with the head '-"60 disposed -'in the enlarged ibore portion 51.

When the parts are assembledin themanner shown in Figures 1 to 5 inclusive, the icetcream dishen is used in the following manner:

The handle 54 is i firmlyl held in ithe hand wvith the thumb engaging the finger-piece 32'and'1the index -finger disposed to bear upon the zfinger By applying pressure of -the index fincream has been scooped into the jcup ll), ?the ratchet *43 will be rotated to impart irotation through'the-gear '3 I to the shaft 9, whichain1turn will rotate the blade 23 over'the innerisurface of the cup I]. By this simple operatio'n,.*atmeasured portion of icecream may be'f'scoopedzfrom an ice cream 'container and subsequentlydislodged from the cup.

One of the principalobjects of'ithetinventi'on,

'as before 'stated-isin-the method or assembling the ice cream dis'her. This affords economical manufacture and may be doneby'one' other "than a skilled mechanic.

' in the following manner:

"Firstjithe"blade 23 ismounted with the pin 26 Linthe opening 21 and'with the angled'end portion '22 -projecting through the opening the bearing 40. The ratchet plate 43 is then mounted on the bearing stud 40 by sliding the slot 45 past the flat sides 43' of the core 42 so that the opening 44 engages the core 42 of the bearing stud 4D, and then rotating the ratchet plate 43 approximately to operative position. While in operative position the ratchet plate 43 cannot become disengaged from the bearing stud 40 because of the fact that the flat sides 43' of the "core '42 are substantially perpendicular to the axis of the shank 12. Next the shaft 19 is mounted in position with the angled end portion 22 of the "blade 23 projecting into the bifurcated end 20.

."ILhesgear 3| is now positioned on the flattened end 29 of the shaft with a tooth 41 thereof engagingirrone of the openings 46. The spacing sleeve 'seen that 'a single ibolt, to= wit,1.the "bolt 58,--serves to connect the :several parts :in assembled r-elation with-respe'ctato each other.

Should occasion: requireithet-replacement of the blade 23 or, for example, the replacement-of the ratchet plate-43:or:.spring 4:8,1the;method .of assembly hereinbefoiredescrihedzpermits these parts to be r disassembled withoutwthe i necessity for the use of tools or the' remova1 o'f thehandlerdt and this is accomplished in'zthe :following manner:

To disassemble :thesezparts-the .blade 23,:being of resilient :material, :may .cbe flexed eto permit withdrawal of the extension (22 from -.the :bifurcated slot' 2| o'fitheishaft'i'fi; whereupon-thisshaft 28 maytbe withdrawnirom theripening 35ll-2Ofilih6 gear 3 I, after which the "gear 23 l z'may "be nd-isen- 'gaged from'the ratchet rplate permitting the ratchet plate 43 to:be..removed from ithezmounting stud 40, 'thus exposing :thetspring =48 :'for tiremoval from the stud-=41! .In achis :disa'ssembiy "of the partsjit will be apparent-that IIOitOOliDI'; other instrument was required.
